I got a file today .txt, within it one of the columns is encrypted. I have already imported it into SQL Server 2012.
The client gave me chave and told me it was encrypted AES 128 ECB
How do I decrypt this column?

You will probably decrypt outside the database, ie in your application layer. The database column will remain encrypted and you can, in your application, use the key it passed to read the data as soon as they arrive from the database.

I understood, but I do not use application layer, I will only perform the select directly in the same bank, without any application.
